Still not sure what he thinks "we" were wrong about. Reading between the lines, since I missed it if he ever said outright what he means, it seems like he means "we" were wrong about a free exchange of ideas on the Internet necessarily leading to only positive developments.

I'm not sure he can speak for Brand and Kelly and others on this. Perhaps they realized, unlike him apparently, that things will be a little messy along the way, a kind of imperfect muddling toward maturity for society. That doesn't make their cheerleading for it something to apologize for.
